Key stage 3
Pupils should be taught to:
  • design, use and evaluate computational abstractions that model the state and behaviour of real-world problems and physical systems
  • create, reuse, revise and repurpose digital artefacts for a given audience, with attention to trustworthiness, design and usability
  • understand a range of ways to use technology safely, respectfully, responsibly and securely, including protecting their online identity and privacy; recognise inappropriate content, contact and conduct, and know how to report concerns

Description

Once your students have completed at least five lessons of Programming 101 or equivalent coding experience, you can assign these CCSS-aligned projects to complement your teaching on topics in geometry, measurement units, fractions, probability, and more. For example, if you’re teaching a lesson on probability, you can assign the Dice Rolls project. Your students will use coding to create a simulation of dice being rolled, then explore the probability of different outcomes by programmatically rolling a die hundreds or thousands of times.

With this collection of math projects, you can easily integrate coding and project-based learning into your curriculum. Each STEM lesson walks students through how to make a project about something they’re learning in school with step-by-step instructions. At each step, it encourages them to make their project unique and interesting, emphasizing that coding is a creative medium much like writing or drawing.

We’re constantly updating our STEM courses with new projects, so if there’s something you’d like us to add, send us a message at support@tynker.com.

What Students Learn

  • Use programming for math projects
  • Build a slide show on a topic
  • Build a quiz game
  • Make an interactive chart
  • Use animation to illustrate
  • Narrate using your own voice
  • Use the physics engine to model
  • Troubleshoot and debug programs
